1925. Serial No. 51,140."

The presentinvention relates to an apparatus for treating textiles, and is particularly an improvement over the apparatus disclosed in my copending application Serial No. 7,932, filed February 9, 1925, which has matured into Patent No. 1,577,393 this application being a division of application Serial No. 36,558, filed June 11, 1925. I

It is an object of the invention to provide an apparatus for mercerizing cotton or similar textiles which will be economical and efficient, saving both time and expense, and

also obtaining highly satisfactory results.

Another object is to provide novel means for and method o f treating the textile goods subsequent to the subjection of the goods to hotcaustic baths and cooling effects, in order to obtain several advantages in the processing and results obtained, including the thorough stretching of the wise stretching of the goods, the thorough washing of the goods and the recovery ofthe I caustic soda. I

With the foregoing and other objects in will be apparent as the invenfully explained, the invention features of the apparatus and View, which tlon 1s more resides in the method as hereinafter pointed out and which is heated. to a temperature claimed, it being understood that changes and variations can be made within the scope of what'is claimed without departing from I the spirit of the invention. The invention is illustrated in the accompanying drawing, wherein the figure is a diagrammatical view, portions being shown in side elevation and portions in vertical section.

In the embodiment of the invention as ,illustrated' and described, the apparatusis intended especially for the treatment of cloth or woven textiles.

In carrying out the process, the cloth 10 coming from the singer moves through a tank 14 containing hot caustic soda or potassium solution, or other alkalinesolution, up to 100 degrees Celsius or centigrade. The cloth moves in a zig-zag path within the tank 14 downwardly and upwardly repeatedly into and out of the solution, by passin around the upper and lower rollers15 an after h the solution in passing throng tank 14 the cloth passes through a cold goods with-. the control of the .length-' '16, and the caustic soda or similar solution in a companion tank 17, squeezing rolls 18 being disposed between the two tanks between which the cloth passes so as to squeeze the solution from the cloth back into the tank 14. From the rolls 18 the cloth passes under rollers 25 submerged in the solution in the tank 17, and from the rollers 25 the cloth passes partly around a roll 22 of a mangle 23. Said mangle has a second roll 26 (and more rolls if desired) and the cloth passes between said rolls 22 and 26.

After leaving the mangle 23 the. cloth.

passes around, in a zig-zag' path, a series; of cooling rolls or drums 27 which cool the cloth down to the required temperature'of about 5 to 10 degrees Celsius. This cooling of the cloth is essential in order to obtain the mercerizing of the cloth, inasmuch as the use of the hot caustic solution will'not mercerize the cloth. However, by subjecting the cloth to the cooling effect after the hot caustic baths, the cloth will be mercerized, and the temperature of the rolls 27 is regulated and controlled'to produce a uniform cooling of the cloth to the desired low temperature. These rolls 27 may be cooled in' any suitable manner, such as by passing cold water through them, as disclosed in the aforesaid application Serial No. 7,932.

From the rolls or drums 27 the" cloth passes to expanding rollers 28, whichexpand or stretch the cloth. I As described up to this, point, the process is somewhat similar to that disclosed in the aforesaid application, Serial No. 7,932, and the apparatus 'andprocess are modified as vwill presently appean' Between the mangle 23 and cooling rolls 27 ,the cloth passes over guide rollers 40 and under a guide roller 41, the guide roller il-being partly submerged in water contained in a water box or tank 42. Also, between the drums 27 and expanding rollers 28, the cloth passes under a guide roller 43 partly submerged in water in a water box or tank 44. The cloth in passing through'the water .in the boxesor tanks 42 and 44 will' assist in gelatinizing the Cloth which is impregnated with the strong caustic soda. By'the use of the cold caustic soda solution in the tank 17 thev cloth is cooled somewhat after being subjected to the hot nuinber of cooling drums ar -rolls 27 re caustic soda baths, which will reduce the A produce the lustre, and the greater the.

-amount of stretch in the width and length of the cloth, the greater will'be the lustre ob- "tained.

I From the expanding'rollers 28 the cloth passes through a heavy geared mangle 63 consisting of a number of rolls of rubber, wood, iron or other suitable material. As

shown, there are five superposed rolls 45,46,

47, 48 and 49. providing fou'r'nips. The rolls of this mangle areeunder heavy pressure to mash or squeeze the .cloth tightly between them. N, 1

. From the expanding rollers 28, of which there areefive as shown, the cloth passes between the mangle rolls 45 and 46 in orderto subject the cloth to heavy pressure after;

leaving the stretching rollers 28, so as to set the stretch in the cloth. 'The cloth then passes around a guide roller 50 and a second set ofexpanding rollers 51, and "from the rollers 51 passes between the mangle rolls 46 and 47. The stretching rollers 51. again stretch the cloth and the mangle rolls 46 and 47 press the cloth in order. to set the stretch therein obtained by the rollers 51. T1118 stretching and pressing of thecloth is repeatedsev'er'al times. Thus, from the rolls 46 and 47 the cloth passes around a guide roller 9 52 and another set of stretchin rollers 53, ",from which the cloth passes etween the mangle rolls 47 and 48. The cloth then passes around a guide roller 54 and a fourth set of stretching rollers 55, and then between i the mangle rolls'48 and 49. Thestretching rollers 28, 51, 53 and 55 maybe of any suitable kind, being preferably of the kind dis- ,closed in said application Serial No. 7 ,932, and also in m copendingapplication Serial No. 751,135, led NOV.20, 1924. Thus, before the cloth passes through each 'of the our nips of the'ma ngle it is stretched/or expanded, in order to stretch the cloth and set the successive stretches in the cloth. However, it is not possible to set the'full stretch in any cloth, and the cloth contracts somewhat notwithstanding the application of high pressure. Consequently the stretching and squeezing is. repeated to obtain a maximumstretch.

. From. the last roll 49 of' the mangle, the cloth passes over j a guide roller 56 and thence downwardly under guide rollers 57 and 58 in succession, for the return of the cloth throughthemips ofthe {Da gle and masses corresponding stretchers. Thus, from the roller 58 the cloth again passes between the rolls 45 ,and 46, e2; anding rollers 51, mangle-rolls 46 and 4 expandlng rollers 53, rolls-47 and 48 expanding rollers 55,

and rolls 48 and 49. This operation is re- ,peated several times. As shown, the cloth is returned four times to the mangle, so that there are five layers or thicknesses passing through the mangle and ex anders. Thus, after reaching the roll 49 t e second time,

the cloth passes guide rollers 56 and 57 and under the roller 58; after reaching the roll 49 the third time the cloth asses over guide rollers 56 and 57 b and un er the roller 58; and after reaching the roll 49 the fourth time, the cloth passes guide-rollers '56? and.

57 and under the roller 58. After reaching the roll 49 the fifth time the cloth passes through the pot eye 62.v The rollers 56, 56,

56 and 56 are located at the top while the rollers 57 57 57 and 57 are located at the bottom, with four vertical runs of the cloth between'the upper and lower setsof rollers spaced apart. Spray pipes59 are disposed between the vertical runs of the cloth be.-

tween the upper and lowerrollers 56, 56,

59 against the cloth, so as to wash the cloth and remove the caustic soda therefrom.

Water spray pipes 60 are also preferably.

panded and before ing operations. Fromthe pot eye 62 the during the expanding, mangling and washn6 cloth is run into the usual kiers (not shown) or if the cloth is intended toi be r6lled,a rolling attachment may be used. I a

The le hwise stretch of the cloth is obtained by" allowing the mangle -63 to run attrifle faster than the rolls 22, 26, .27 and l passes before reachmg the mangle 63. Fur.-

thermore, the cloth has a tendency to shrink other parts of the apparatus which the cloth a if cloth is thereforestretched lengthwise as it passes through the apparatus. When passing each set of expanding rollers the cloth is not only stretched in width but is also given a longitudinal stretch because of the transverse tension. On account of the stretched condition of the cloth and the tendency for same to contractboth longitudinally and transver y e r ing ea h setrot exa maximum stretch, but on account of the contraction of the cloth after leaving the set of expanding rollers the stretching effort must be repeated, and the stretching action is repeated simultaneously on the several layers of the cloth in'the mangle 63. The

simultaneous stretching of several layers is of. advantage, inasmuch as the layers contact tightly with one another and have a tendency to assist one another in thestretche ing and settin actions. Thus, during therepeated stretching and setting actions there is a repetition in the efiort to bring-the cloth to a maximum stretch. If no washing of the cloth is desired by means of the spray pipes 59 and 60, the tank 61 will collect a, stron c'austicsoda solution squeezed from the cloth filtration, be used ,over ,again.

This process and apparatus provide for increased production, and a reduction inthe number of attendants or workmen. The

cloth will be thoroughly stretched without injury, j both transversely and lengthwise,

and t is possible to control the stretch in length. By running the cloth two or more thicknesses through the mangle 63 and stretchers, each fibre in the cloth receives a stretching action. Furthermore, the cloth is mashed and the interstices closed up by the manglingbperation. For cloth to be bleached, no water for washing is necessary, inasmuch as the passing of the cloth repeatedly through the nips of the mangle 63 will squeeze out the necessary caustic soda, leavingonly enough in the cloth re uired for the boiling operation preceding t e bleaching.

The recover of the caustic soda in the cloth is simplifie and subsequent operations of calendering in many cases are unnecessary. Furthermore, the apparatus requires comparatively small spaoe, and the operationis continuous from the singer to the kiei's. Less materials are required for the treatment of the cloth than with previous processes,

. and the results obtained are favorable,

It. is possible to use' the apparatus and process for the treatment of yarn, inasmuch as yarn maybe run through the apparatus,

and the apparatus may be simplified or modified, if desired, when used for yarn only.

- When treating yarn the longitudinal stretching thereof is employed, without transverse stretching, and this may be obtained either by the tendency for the yarn to shrink lengthwise, or the rollers which the yarn passesin succession may be run at higher speeds in progression, such as suggested hereinbetore to obtain the longitudinal and this liquid can, after simple stretching of the cloth. The yarn in being returned through the mangle 63 may have the adjacent portions bunched or held together, either in layers or disposed side by side.
